You have to find the domain and range

Dahasolnce [82]

Answer:

First off, we look for which circles are open or closed.

We start with an open interval since the circle on the left is open and end with a closed interval since the circle on the right is closed.

Domain is all x values, Range is all y values

The graph shows the continous function going from -3 to 1 on the x axis.

According to the circles, this means our domain will be (-3,1].

Now, the range doesn't care about if its closed or not. So we can say the graph is on the y axis from -4 and 0. This means the range is -4<y<0

I used different notations for both just incase you need to represent your answer differently :)

-3<x<1 & (-3,1] . Range is [-4,0]. 0>y>-4 looks correct as-well.

4.. Please help. Is DE←→ perpendicular to FG←→? Why or why not?

olya-2409 [2.1K]

Given:

DE contains the points D(1, -2) and E(3, 4).

FG contains the points F(-1, 2) and G(4, 0).

To find:

Is DE perpendicular to FG.

Solution:

Slope of DE:

$$m=\frac{y_2-y_1}{x_2-x_1}$

Here $x_1=1, y_1=-2, x_2=3, y_2=4$

$$m=\frac{4-(-2)}{3-1}$

$$m=\frac{6}{2}$

m = 3

Slope of FG:

$$m=\frac{y_2-y_1}{x_2-x_1}$

Here $x_1=-1, y_1=2, x_2=4, y_2=0$

$$m=\frac{0-2}{4-(-1)}$

$$m=\frac{-2}{4+1}$

$$m=\frac{-2}{5}$

<em>Two lines are perpendicular if product their slopes are -1.</em>

Slope of DE × Slope of FG

$$=3\times \frac{-2}{5}$

$$= \frac{-6}{5}$

≠ -1

The solution is no, because the product of the slopes is not -1.

He collected a total of 225 . If 68% of the stamps he collected were foreign, how many other stamps did he collect?

MissTica

Answer:

72 stamps

Step-by-step explanation:

First, we're looking to find the number of stamps that AREN'T foreign, so we have to subtract 68% from 100%.

100% - 68%
32%

Now, we know that 32% of the stamps are NOT foreign. So, next, we:

Multiply 32 by 225.
Divide the product of 32 and 225 by 100

$32*225$
$7200$
$7200/100$
$72$

Therefore, the answer is 72 stamps.
